To all whom it may concern:

Be i known that I Joan S. Tmmguan, citizen of the United tates, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Dust- Receptacles, ,of which the following is a full, clear, and exact description, re erence forming a part hereof. My unvention has relation to improve ments in dust receptacles or' separator tanks to be used in connection with vacuumcleanin systems; and it consists in the novel deta s of construction more fully set forthin the specification and pointed out in the claims. 4

In the drawings, Figure 1 is a top plan of the receptacle, parts being broken away;

Fig. 2 is a combined elevation and section on the broken line 2-2 of Fig. 1, parts being broken away; and Fig. 3 is an enlarged sectional detail on the line 3-3 of Fig. 1.

The present receptacle, though serviceable in con unction with vacuum cleaning systems generally, is eminently adapted for use on rallway cars, making a highly usefuladjunct to a car equipment- The object is to'provide a receptacle which a is portable, the same having provision for connecting it to a compressed-air hose derivmg'its supply from the tank on the car from which the air-brakes are operated.

' receptacle 1s theexhauster, the jet nozzle of Entering as a construction feature of the which is connected to the compressed-air hose above referred to, the discharge nozzle of the exhaustei' being secured directly to the receptacle wall, and projecting a suit-. able distance into the receptacle, and to a point under the 'open end of the'filter bag confined therein.

A further object is to rovide a' receptacle which will effectively lter the dust laden air projected into the same so no dust shall escape into the car or compartment where the cleaning is taking place.

The invention possesses further and other advanta es better ap arent from a'detailed description thereof w ich is as follows:

Referring to the drawings, 1 re resents thelower section of the receptacle, (t1 3 same provi c with being made of sheet iron, an an upper inner stiffening ring of angle iron 2, the bottom 3.bein raised slightly above the lower edge of sai section 1 so as to 0011-.

veniently accommodate the screw disk or door 4, the latter being in the form of an inverted cup provided with a central knob by which it may be conveniently manipulated. Restin on the angle-iron ring 2 is a ring 6 shoul ered a ainst the inner edges of the horizontal mem r thereof to prevent displacement and makingan air-ti ht 'ointtherewith, said ring bein provide wit an upwardly extending annu ar collar or-flan 7 having a terminal bead a below which 15 .assed around the flange the elastic or rubr band 8 at the edge-of the dust sack 9, the band serving to hold the sack in place on the flange 7. This sack is composed 'of any suitable fine-mesh material such as duck canvas, burlap or equivalent material as well when fully extended .tomore than ii the lower compartment of the upper section 1' of the receptacle. The section 1 is provided-at the bottom with an inner stiffening angle-bar ring 10 resting on the ring 6 an making an air-ti ht 'oint therewith, and is provided with a an le or bail 11 by which it can be raised for purposes of access to .understood in the art, and has a ca 'acity I the sack. The top of the section 1 is dome- I shaped and perforated to'allow for the escape of the filtered air, and recaution is taken against the closing up 0 the. erforations by the sack 9 when distende under the action ofthe air-currents entering the receptacle, by lacing tin-intercepting wire screen 12 at t e base of the dome or roof of the receptacle,-said screen being preferably-secured in place byangle-lgennketg 1:2: an e as When the two sections 1, l sack supportingring 6 are properly assembled, the sections are clamped together by means of the locking links or tees 14 swung between brackets 15, 15 riveted to the lower section 1, the free ends of the links having screw-threaded stems which pass into recesses (1 formed on the horizontal arm of an angle-bracket 16 riveted to the up er sec-. tion, a terminal clampin screw 1 being uickl driven home a ong the screwt rea edstem of the link against the bracket arm, when the parts are firmly drawn together. They may as quickly be. taken apart. 1

Located along the inner wall of the bottom section 1 is a reinforcing plate 18 op- 'posite which is riveted to the receptacle the anged base of a discharge nozzle 19 throu h which the dust-laden air is rojecte into the receptacle against the p ate hose or air line H leading 'to any suitable suction head or renovating tool (not shown) by which the cleaning is effected, as well understood in the art. The other leg of the'Y is coupled to a compressed air suppl hose S leading to an source of compress air supply (such as t e com ressed alr tank on the car used for air-bra e service), the

said second leg being provided with a jet nozzle 22 disposed along the axis of the nozzle 19, a suitable constriction being formed around'the nozzle 22 so as to draft the air from the air line or hose H at an increased velocity at the point of such constriction, the dust-laden air'current thus induced, and the com ressed air-jet from the nozzle 22 conjoint y flowing through the nozzle 19 into the receptacle where the air is filtered, the dust drawn through the cleaning tool and projected into the sack 9 being removed from time to time as occasion demands. The distension of the sack under the force of the current within the receptacle finally brings the sack into contact with thediaphragm or screen 12 by which it is prevented from bearing against the dome of the rece tacle and closing the perforations 0 ther'eo which should at all times be free to the passage of the filteredairh By unscrewing the cap or disk 4, the dust recaifi; itated by contact with the sack and w of the receptacle may be easily dumped out.

The formation of the receptacle in se arable sections as shown, and the detacha le 7 character of the dust-sack make the device eminently adapted for railway service, since the porter may readily disassemble the parts, and clean them separately either from the car-platform or in the closet adjoming the wash-room. The exhauster (comprising the nozzles 19, 22, and connection 20) being cou led directly to the receptacle disgenses wit the necessity of attaching this tting to the hose.

section and an upgersection forming an ex-- the escape of air, a renfovable imperforate member interposedbetween the sections and savided with a flan removed a suitable ance from the wa "of the receptacle and projecting into the u per section of the receptacle a sack co ed in the up er sectlon and having its open end secur to the flan of the member confined between the sections, and an exhauster secured to the lower section and discharging thereinto and into the sack.

2. ,A dust-receptacle comprising a lower section and 'an upper section having a perforated top,angle-1ron rings at the adjacent ends of the sections, a ring inter osed between the sections and shoulder a inst and resting on the horizontal arm of't e angle-iron rm of the lower section, a flange on the sho dered ring, a bead on the end of the flange, adust-sack having its open end passed about the flan e, and pro'ectm into the upper section of t e receptacle, an

' an exhauster dischargin dustladen air into the lower section an into the sack.

3. A dust-receptacle comprising a lower section and an upper section forming an extension thereof and having top perforations, a removable member interposed between the sections and provided with a flange removed a suitable distance from the walls of the receptacle and projecting into the up or section of the receptacle, a sack confined 1n the upper section andhaving its open end secure fined between the sect-ions, and an exhauster secured to the lower section and discharging thereinto and into the sack.

4. A dust-receptacle comprising a lower section and an upper section forming an extension thereof and having to perforations, a removable rin interpose etween, the sections and provided with a flange removed a suitable distance from the walls of the receptacle and projecting into .the up er section of the receptacle, a sack confined to the flange of the member con in the 1' upper section and having its open and se-' cured to the flange of the ring, a perforated diaphragm inte osedbetween the sack and perforated top 0 the upper section, and an exhauster secured to the lowersection and discharging thereinto and into the sack.

In testimon whereof I aflix my signature, in presence 0 two witnesses.
